The discovery and synthetic applications of a widely applicable and highly enantioselective (>99% ee) protocol consisting of the 'ZACA reaction' (Zr-catalyzed asymmetric carboalumination of alkenes), purification of the ZACA-products by lipase-cat....

The role of nitric oxide in cellular signaling in the past three decades has become one of the most rapidly growing areas in biology. Nitric oxide is a gas and a free radical with an unshared electron that can regulate an ever-growing list of biolog....

As a student in the early 1960s, I had the privilege to attend winter seminars organized by my mentor, W. Hoppe, and by M. Perutz, which took place in a small guesthouse in the Bavarian-Austrian Alps. The entire community of a handful of protein cry....

In the process of preparing M(NR)(CHCMe2R')(OR")2 (R' = Me or Ph) species (or analogs that contain enantiomerically pure biphenolate or binaphtholate ligands) in situ by treating M(NR)(CHCMe2R')(pyrrolide)2 species with alcohols, we have discovered M....

Much of theoretical chemistry has involved equations and their application to experiments, Debye, Debye-Hueckel, Transition State Theory, Kramers, LCAO, RRKM, among others. In fortunate circumstances one can, as in a theory of electron transfer reac....

Chemistry is not merely a science of making observations in order to better understand Nature. Our science is creative and productive, generating substances of very high value from almost nothing. Chemists already have made enormous contribution to....

The interaction of molecules with the surfaces of solids forms the basis of heterogeneous catalysis and can now be investigated in atomic detail. Systems of this kind may, on the other hand, serve as models for studying self-organisation of matter le....

The palladium-catalyzed cross-coupling reaction between different types of organoboron compounds and various organic halides in the presence of base provides a powerful and general methodology for the formation of carbon-carbon bonds.  The (sp3)C-B ....

Olefin metathesis is an irresistible way to make C=C bonds catalytically in organic molecules and polymers, both as a consequence of its very nature, i.e. the synthesis of C=C bonds from C=C bonds, and because of the control that can be exercised thr....
